Application filed July 15, 1919. Serial No. 311,051.

To all whom t may concern.'

Ee it known that l,-FnANots GAsooreNn Lrnou, subject ot the King of Great Britain, and resident of rlhe lllaves, llicardy liiill, Belvedere, Kent, England, have invented certain new and useful improvements in and Relating' to Concrete Slabs tor the Erection ot Cellular Structures, of which the tollowing,` is a sgeci'lication.

This invention is an improvement in or moditieation oit that described and claimed in the application for Letters Patent Serial lliunber 311,049, tiled July 15, 1919.

ln my atoresaid specification l described the erection ot reinforced concrete structures by means ot concrete slabs which are so arranged relatively to each other during` erection that the horizontal joints in alternate vertical series ot' slabs are sta gered relativelyY to each other as bythis means each individual slab-except those composing,1 the loivermost and uppermost portionsol the. structure is supported and stiftened by the maximum number oi juxtaposed slabs. By arranging the horizont-al junctions or joints in this manner a veryy firm and strong structure ensured and the slabs being,v ready prepared `are at once held in a vertical and true position 'tor the next oncoming slab to secure and permanently lock the preceding slab so that the erection is capa-ble ot accomplishment with truth and expedition.

Now it is the object ol the present invention to provide an improved construction oit slab which while retaining; the characteristics ol the slabs above re't'erred to in so lar as the disposition ol" the horizontal joints is concerned shall be adapted tor the soeedy erection ol hexagonal cellular concrete structures.

VWith this end in view my present invention consists primarily in torining the slabs in such a manner that any two slabs when arranged in angular juxtaj'uisition to ttorm a portion oit an hexagonal structure will present in'the direction ot their vertical edges a recess adapted to receive the vertical edge oit' a third slab.

More specilic-ally considered my invention consists in forming the edges of the slabs with oppositely disposed bevels arranged at an angle of 1200 to each other so that any two slabs when arranged in angular juntaposition to form a portion or" an hexagonal structure will present a 6bird-mouth adapted to receive the vertical edge of a third slab similarly iormed. il further and subsidiary feature ot the invention consists in the improved means it'or bending;` the vertical joints ol `an hexagonal cellular structure erected in accordance with the primary feature oi' the invention and which will hereinafter be more specifically described.

ln order that the the-'said invention may be readily understood and carried into effect same will now be more fully described with reference to the accompanying drawings in which- Figure 1 represents a perspective view'of a slab for the erection othexagonal cellular structures under this invention.

Figure 2 is a diagrammatic plan View 01"' three slabs two or" which are juxtaposed to term a portion ot' acell of hexagonal form whilst the third slabv is shown as spaced therefrom to illustrate the recess 'formed by the two slabs for its reception.

Figure 3 is a perspective View of three slabs under this invention. arrangedl in anlQular relation to form part of an hexagonal cell.

Figure l illustrates in plan a portion ot' an hexagonal cellular structure constructed according' to this invention.

Figures 5 and tl are detail views hereinaiiiter more particularly referred to.

ln the erection otf an hexagonal structure under the present invention those edges of the slabs 1 which when said slabs are erected constitute their vertical edges are formed with oppositely disposed bevels 2 arranged at an angle olfA 1290 so that, as will be clearly seen. by reference to Figure 2, when two slabs are arranfred in angular juxtaposition a recess or ibirdmouth 3 is formed adapted to receive the similarly bevelled edge ot a third slab, lly constructing the edges in this manner not onlj,T will each slab be neld in place immediately when it is bedded in position but it will also be retained vertically by the two adjoining` slabs by reason of the birdniouth recess 3 betere mentioned.

Preferably each slab 1 is formed during manufacture with one or more recesses l in its edges so disposed that when the slabs are juxtaposed said recesses will register (see Figure and these recesses are utilized as a means of effecting the bending of the slabs together at the vertical oints. To this end appropriate vertical centering 5 (Figure 5) is arranged across the angles of the. cells and secured in position by metallic Wire or rod 6 Which passes through the centering and through the atoresaid recesses il or alternatively through holes 7 (Figure 3) drilled in the slabs. Fat concrete 8 is then-poured bet-Ween the centering 5 and slabs l Which when .set forms fillets and sen curely bonds the slabs together and makes a tight joint between thein. The Wires 6 are then cut at the points 9 (Figure 5) and the centering 5 removed. j

ln` the slightly modified form of vertical joint illustrated in Figure 6 the vertical edges of the slabs, are bevelled in the opposite direction tothat shown in the other t`1gures or the drawing that is to say each vertical edge ornis in itself a birdrnouth" recess so that When three slabs are arranged in juxtaposed position a key l0 may be inserted and fat concrete or cement poured around it to bond all lirinly together.

l clairn:

l. An hexagonal cellular structure cornprising concrete or like slabs, oppositely bevelled vertical edges on said slabs the vertical edges of one slab Awhen arranged in juxtaposition to the vert-ical edges of another slab forming with said vertical edges a recess to receive the vertical edges of av third slab, and a recess in the vertical edges oit each slab.

2. An hexagonal cellular structure coniprising concrete or like slabs, vertical edges thereon oppositely bevelled at an angle of 120O the vertical edges of one slab When arranged in juxtaposition to the' vertical edges of another slab forming with said vertical edegs a recess to receive lthe vertical edges of a third slab and a recess in the vertical edges ot each slab. v

3. An hexagonal cellular structure coniprising a series of vertically arranged slabs,

oppositely bevelled vertical edges on said slabs, a recess in each of said slabs, a second series of vertically arranged slabs oppositely bevelled vertical edges on said slabs one ver# tical edge ot' said series being arranged in juxtaposition to one vert-ical' edge ct said tirst series or' slabs, a recess in each of said second series or' slabs, a third vertical series of slabs, oppositely bevelled vertical edges on said slabs, one of said vert-ical edges being arranged in; juxtaposition to a vertical edge cit vsaid irst series oit slabs, and the other vertical edge of said third series oit slabs being arranged in juxtaposition to a vertical edge of said second series of slabs, a recess inl each of said slabs, the recesses in the slabs registering'with each other and a lling of concrete in said recesses.

et, An hexegonal cellular structure coinprising a series of vertically varranged slabs vertical edges on said slabs oppositely bev elled at an angle oi 120o a recess in each of said slabs, a second series ot vertically arranged slabs vertical edges on said slabs oppositelj7 bevelled at an angle of 12()O one vertical edge of said series being arranged in juxtaposition to a vertical edgein said lirst series, a recess in each of said series of slabs, a third vertical series ot slabs, vertical edges on said slabs oppositely bevelled at an angle of 1200 one ot said vertical edges being arranged in juxtaposition to a vertical edge of said lirst series of slabs, and the other vertical edge ot said series being arranged in uxtaposition to a vertical edge of said second series or slabs, a recess in each oi"- said third series ot' slabs the recesses in the slabs registering with each other and a filling ol concrete in said recesses.
